Lower Bangor Limestone Locality 2 (Carboniferous of the United States)

Where: Franklin County, Alabama (34.5° N, 88.0° W)

• Paleocoordinates: 21.6° S, 36.9° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: lower Member (Bangor Limestone Formation), Pendleian (330.9 - 327.0 Ma)

• "in beds approximately 18 m above the underyling Hartselle Sandstone, in cross-bedded channel fills" (shown in figure as Chesterian and roughly equivalent to the Glen Dean or uppermost Middle Chesterian = Pendleian)

• group of beds-level stratigraphic resolution

Environment/lithology: deltaic; lithified, calcareous, carbonaceous sandstone

• lenses "represent possible tidal or deltaic channel fills, interbedded in shales in the lower part of the formation"
• "local cross-bedded, sandy limestones and calcareous sandstone lenses" (also described as "fine-grained sandstone" and including "abundant dark-brown to black, carbonaceous fragments")

Size class: macrofossils
